Totally blank black screen??

Ok sooo I decided to get into the Christmas mode and download a new theme on my rooted droid. So I had U.d. 2.3.0... and I saw there was a new 2.4.0 So I flashed that on there, after having to reformat my card. Then I tried to flash the theme and it said everything went fine and I went to reboot, and it went to the Motorola logo like usual and then it acted like it was going to show the boot screen but there is nothing. Its just kinda froze! Does this mean its bricked???? What do I do!!!!

First I would make sure your SD card is seated right. Then try to reboot and go into recovery. You said you made a nandroid? But the very first thing to do is call me so I can umm.....walk you through the fix....

LOL Ok I will call you prolly tomorrow night and get some help with it. I have tried re seating the card I have tried just about everything. It won't let me mount the card, It won't let me enable mass storage and it won't let me do a restore. They all give me Errors

Step one at this point is trying a new SD card. It sounds like the one you have is totally dead. Make sure the contacts on the card are clean (use a toothbrush) and try it in a card reader or another device to see if that device or reader can recognize it. If so there may be something wrong with your recovery image or phone. But try another card in the phone.
